Definitions

  • the present invention relates to a method and equipment for manufacturing a thin, hollow glass item, for example such as bottles or any other item of that type.
  • the invention also relates to a hollow glass item obtained using this method.
  • the manufacture of hollow glass items must meet various constraints, and in particular shape constraints, for example the position of the neck, manufacturing tooling constraints, for example for stripping, constraints related to the distribution and weight of the glass, and specific constraints related to packaging.
  • One known method for manufacturing this type of item consists of introducing at least one molten glass parison into a parison mold at a predetermined temperature and preforming the article in the parison mold from said at least one parison by injecting a pressurized gas, for example such as air, into the parison mold.
  • a pressurized gas for example such as air
  • the blank of the item thus produced is transferred into a finishing mold and the item is definitively formed in that finishing mold by also injecting a pressurized gas.
  • hollow glass items and more particularly bottles intended for perfume and cosmetics, have been made with thick glass distributions, which is considered very qualitative and contributes to conveying an image of luxury.
  • the trend is to produce hollow glass items with practically invisible glass walls so as to convey an image of lightness, refinement, elegance and apparent fragility.
  • the adjustment of the parison mold and the geometry of the blank make it possible to obtain glass walls with a thin and regular thickness, but excess glass remains in the bottom of the item, centered on the axis of said item.
  • the invention aims to propose a method and equipment for manufacturing a thin, hollow glass item that avoids these drawbacks.
  • the invention therefore relates to a method for manufacturing a hollow glass item having thin walls and a thin bottom, said method comprising:
  • the invention also relates to equipment for manufacturing a hollow glass item including thin walls and a thin bottom, said equipment comprising:
  • the invention also relates to a hollow glass item having thin walls and a thin bottom, obtained using the method previously defined, characterized in that the side walls have a thickness comprised between 0.5 and 3 mm, preferably of approximately 1 mm, and the bottom has a thickness comprised between 1.5 and 4 mm.
  • FIG. 1 is a diagrammatic view of part of equipment for manufacturing a thin, hollow glass item, according to the invention.
  • FIGS. 2 to 6 are diagrammatic vertical cross-sectional views of the parison mold and the finishing mold of the equipment, respectively, according to the invention.
  • FIG. 7 is a diagrammatic view of a hollow glass item obtained after the forming step in the finishing mold.
  • FIG. 8 is a diagrammatic perspective view of the final hollow glass item.
  • a hollow glass item 30 for example a bottle with a generally parallelepiped shape including thin side walls 31 and a thin bottom 32 , as shown in FIG. 8 .
  • the side walls 31 have a thickness comprised between 0.5 and 3 mm, and preferably approximately 1 mm, and the bottom 32 has a thickness comprised between 1.5 and 4 mm.
  • this equipment also makes it possible to manufacture hollow items with various shapes and a small thickness.
  • the equipment includes a molten glass distributor 1 placed in a furnace, not shown, and a parison mold generally designated by reference 10 .
  • the distributor 1 of the known type delivers, at the outlet of a pouring orifice 2 , a parison 3 which, traditionally, is cut using scissors, not shown.
  • the parison 3 falls into a duct 4 which conveys it to the parison mold 10 including a cavity 10 a for forming a blank 5 .
  • the cavity 10 a of the parison mold 10 includes a funnel 13 at its inlet.
  • the lower part of the parison mold 10 includes a blower nozzle 12 connected to a pressurized gas supply device, for example such as air, not shown.
  • a pressurized gas supply device for example such as air
  • a bottom 14 is placed on the funnel 13 on the upper opening of said parison mold, and pressurized air is injected through the blower nozzle 12 to compact the glass and form a ring 5 a on the blank 5 , as shown in FIG. 3 .
  • the bottom 14 is then raised to make it possible to remove the funnel 13 .
  • This bottom 14 is positioned on top of the parison mold 10 , making it possible to shape the bottom of the blank 5 , and pressurized air is blown through the nozzle 12 .
  • the blank 5 is stripped and transferred by a handling arm 15 ( FIG. 1 ) pivoting around an axis 15 a , in a finishing mold 20 diagrammatically shown in FIGS. 4 to 6 .
  • This finishing mold 20 includes a cavity 20 a , the lower part of which is covered by a removable bottom 21 .
  • This removable bottom 21 makes it possible to shape the bottom 32 of the item 30 to be obtained.
  • the bottom 21 of the cavity 20 a includes a concave hollow 22 .
  • a blower nozzle 23 is mounted on the upper part of the finishing mold 20 , said blower nozzle being connected to a device supplying pressurized gas, for example such as air (not shown).
  • pressurized gas is blown into the blank 5 so as to form the item 30 ( FIG. 6 ).
  • the excess glass is housed in the hollow 22 formed in the bottom 21 of said finishing mold 21 forming, toward the outside of the bottom of the item 30 , a convex bulge 33 , as shown in FIG. 7 .
  • the inner distribution of the bottom 32 of the item 30 subsides in the hollow 22 and the inner face 32 a of the bottom 32 becomes horizontal.
  • the item 30 obtained the finishing mold 20 is shown in FIG. 7 and is stripped from that finishing mold 20 by removing the removable bottom 21 .
  • the operators perform at least one cutting operation followed by at least one polishing operation of the outer face 32 b of the bottom 32 of the item 30 so as to obtain a bottom 32 with a substantially constant thickness, as shown in FIG. 8 .
  • said finishing mold 20 includes at least one vent designated by reference 25 in FIGS. 4 to 6 .
  • each vent 25 is formed by a duct formed in the walls of the finishing mold 20 .
  • Each vent 25 inwardly includes an element allowing the gas to escape, while preventing the molten glass from flowing through that vent.
  • Each vent 25 may be formed by any other arrangement in the finishing mold 20 .
  • Hot and cold chemical treatments may be done on the item 30 so as to reinforce the outer surface of the glass.
  • the method according to the invention makes it possible to be able to obtain a thin, hollow glass item having a homogenous distribution of the glass and having the requisite solidity for this type of item despite the small thickness of the side walls and the bottom.
